Frequently Asked Questions About Heavy-Duty Repair

What are the first signs of a failing turbocharger on a diesel engine?

Common signs include a noticeable loss of power, an increase in black or blue exhaust smoke, a high-pitched whistling sound from the engine, and a lit check engine light. If you notice any of these symptoms, it’s crucial to have it inspected immediately to prevent catastrophic engine damage.

How often does my truck’s DPF (Diesel Particulate Filter) need to be serviced?

The service interval for a DPF can vary widely based on the truck’s make, model, and duty cycle. Typically, a cleaning is recommended every 200,000 to 400,000 miles. However, trucks that do a lot of idling or city driving may require more frequent service. We can assess your DPF’s condition as part of our regular maintenance checks.

Do you offer mobile or roadside heavy-duty repair?

While we provide 24/7 towing to get you to safety, we perform all major repairs here at our fully equipped Batavia facility. Modern heavy-duty trucks are too complex for most roadside fixes. Bringing your rig to our shop ensures we have the diagnostic tools, heavy lifting equipment, and controlled environment needed to perform a safe, accurate, and durable repair that you can depend on for the long haul.
